Yes, Modo is complex but with time, and tutorial study you should be able to learn it.

I also recommend Carrara Pro - it's simple to grasp and you can do a good amount of stuff with it.

The fact it also lets you create environments similar to Vue is a positive as well.

Definitely look around for the free version - you can't go wrong having that installed on your computer.
